JOSEPH M. FOX, OF PEEKSKILL, NEW YORK.

WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. |'6O,327, dated May 17, 1904. application filed August 10, 1903. Serial No. 168,987. (No modeLl To all whom/t may concern:

' Be it known that I, JOSEPH MzFoX, a citizen of the United States, residing at Peekskill, county of Westchester` State of VNew York, have invented a new and useful Tater-Heater, of which the following is a specification.

My invention relates to the class of waterheaters in whichthe water is heated by being passed through a series of sections inclosed in a heating-chamber, it being wholly immaterial so far as my present invention is concerned to what use the heater is applied, whether for water-heating generally or for making steam, or what fuel or type of burner is used; and my invention has for its' general object to simplify and cheapen the construction, to improve the operation in use,'and to greatly reduce the consumption of fuel required to produce a required result, important special objects being to produce a novel form of section that will give a maximum amount of heatingsurface and at vthe same time be relatively easy to cast and to produce a novel form of top plate that will retard the draft and prevent eXcessive radiation of heat from the top of the chamber. i

With these and other objects in View my invention consists in certain constructions and in certain parts, improvements, and combinations, which will be hereinafter fully described and then specifically pointed `out in the claims hereunto appended.

In the accompanying drawings, forming a part of this speciiication, Figure 1 is a vertical sectional view, partly in elevation, illustrating the construction and mode of operation of my novel heater; Fig. 2, a section on the line 2 2 looking down; Fig. 3, a section on the line 3 3 looking down, and Fig. 4 is a section on the line 4 4l looking down.

rlhe essential features of my novel waterheater are a heating-chamber, (indicated by A,) a heater proper, (indicated by B,) and a water-heating section or plurality of sections, (indicated by C.) The special construction of the heating-chamber is not of the essence of the invention. I have shown a heating-chamber having inner and outer walls, (indicated by 10 and 11, respectively,) a bottom plate, (indicated by 12,) and a top plate, which is preferably but not necessarily of special con* struction and which I have indicated by I). The heater B illustrated in the drawings is an ordinary gas-heater having a gas and air supply pipe 13, although, as already stated, the special form of heater used is not of the essence of the invention.

14 denotes the water-supply pipe, and 15 the delivery-pipe. Between these pipes I place one or a plurality of my novel water-heating sections, connected, when a plurality is used, by short pipes 16.

17 denotes spiral plates which I preferably place in the water-pipes for the purpose of giving a whirl to the water as it enters and leaves the sections, so as to break up the colL umn of water as it passes through the sections, thereby insuring that the entire body of water passing through the heater will be brought into direct contact with heating-surfaces.

Each heating-section comprises .lower and upper hubs, (indicated, respectively, by 18 and 19,) an intermediate ring 20, which-may be more orlcss oval in cross-section, as shown in the drawings, and inclined tubes 21, which connect the intermediate ring with the hubs. These inclined tubes are preferably staggered-that is, placed out of line with each other, as shown in the drawings, in which it will be seen that the lower inclined tubes intersect the ring midway between the intersection of the upper inclined tubes with the ring. This construction I find in practice produces better results in heating water to any required degree with a minimum` consumption of fuel than any construction that has heretofore come to my knowledge, it being impossible for the water to pass through the sec-,

that water columns be broken up in each section and practically the entire body of water brought into direct contact with heating-surfaces.

In practice where a plurality of water-heating sections are used I preferably use a spe- `tions in a column or columns, but inevitable cial form of top section, as clearlyshown in` the drawings. (See Figs. 1 and 2.) The lower portion of this section is identical in construction with the other sectionsthat is to say, it

IOO

comprises an intermediate ring and a lower set of inclined tubes. The upper portion oi' the upper section, however, comprises a circular water-chamber, which I have indicated by 25, the water in this section being in a solid body, so that this section, in fact, serves as a bathe-plate and retards, as would any other form of bathe-plate, the passage of air from the heating-chamber. This special form of top section is provided with lower and upper hubs precisely like the other sections.

As already stated, the special form of top plate used is not of the essence ofthe invention. I preferably, however, use a top plate provided with an annular chamber 22, the function of which is to control the escape of heated air from the heating-chamber and prevent the escape or' any air therefrom until it has made a partial circuit of the annular chamber. Another function of this chamber is to prevent radiation or' heat from the top of the heating chamber, as the radiation will be from the annular chamber instead of from the heating-chamber, thus assisting materially in keeping' the air in the heating-chamber at a high temperature with a relatively small fuel consumption. All air escaping from the combustion-chamber must pass into one side of the annular chamber through openings 23, a plurality of said openings being provided on the side opposite to the outlet-pipe, which is indicated by 24, and thence around to the other side to escape through said outlet 24.

Having thus described my invention, I claim- 1. A heater-section comprising upper and lower hubs, an intermediate ring and a plurality of inclined tubes connecting the intermediate ring with the hubs.

2. A heater-section comprising hubs, a ring lying intermediate said hubs, said ring being' oval in cross `-seetion, and a plurality of inclined tubes connecting the intermediate ring with the hubs.

3. A heater-section comprising hubs, aring lying intermediate said hubs and inclined tubes connecting said ring with the hubs,.said tubes being placed out of alinement with eachother, substantially as shown, for the purpose specitied.

4. In a heater of the character described the combination with watersupply and delivery 6. In a heater of the character described 4the combination with water supply' and delivery pipes, of water-heating sections each consisting' of hubs, a ring intermediate the hubs and inclined pipes connecting the ring and the hubs, and water-pipes connecting the sections each of which is provided with aspiral plate."

7. In a heater of the character described the combination with water supply and delivery pipes and an intermediate water-heating section, of a heating-chamber comprising a'bottom plate, inner and outer walls and a top plate having an annular' chamber, openings into said chamber and an outlet-pipe opposite said openings.

8. An upper heater section comprising hubs, a ring l yinginterrnediate said hubs,a plurality oi inclined tubes connecting the lower hub with the ring and a circular water-charnber intermediate the ring and the upper hub.

In testimony whereof I affix my signature in presence of two witnesses.
